3 Claims.

The present invention relates to a support arrangement for an X-ray tubeand X-ray filming equipment.

v One object of the invention is to provide supports for the X-ray tube and for the photographic equipment which permit various adjustments of the supported elements in such a manner that their focal axes remain always in a predetermined vertical plane.

Another object of the invention is to provide supports which can be easily transported to various points in a room while retaining the focal axis of each piece of equipment in a predetermined vertical plane.

A still further object of the invention is to provide an arrangement in which the support for the X-ray tube nd that forthe photographic equipment are displaceable relative to each other along parallel tracks, the X-raytube and the photographic equipment being adjustably carried by their respective supports so as to have their focal axes always disposed in one and the same vertical plane parallel to and between the support tracks.

Still another object of the invention is to provide, in combination witha support arrangement in which the support for the X-ray tube and that for the photographic equipment are dis placeable along parallel tracks,- as described, an X-ray table displaceable along a'third track extending parallel to and between said first two tracks, and' capable of being inserted between the X-ray tube and the photographic equipment.

My prior U. S. Patent 2,205,853 described photographic equipment suitable for the filming of X-ray images and the photographic equipment referred to in the present specification may be of this type, but it will be understood that other photographic equipment capable of serving the same purpose may be substituted.

The principal features of my invention are set forth in the following description, defined in the appended claims and illustratively exemplified in the accompanying drawings, in which Fig. 1 is a side view of a support standard according to the invention carrying photographic equipment substantially as described in my prior U..S. Patent 2,205,853;

Fig. 1A is a left hand end view of Fig. 1;

Fig. 1B is a top view of Fig. 1;

Fig. 1C is a side view similar to that of Fig. 1 with the photographic equipment adjusted to a different position;

Fig. 2 is a side view of a support arrangement tion to the support for the photographic equipment, a similar support for theX-ray tube and an X-ray table, the latter being in an inoperative position at the right hand side of the figure;

Fig. 2A is a top view of the arrangement according to Fig. 2 I

Fig. 3 is a side view similar to that of Fig. 2 in which the X- ray tube and photographic equipment are adjusted to an inclined working position and the X-ray table is placed, in a similarly inclined position, between the X-ray tube and the photographic equipment, and

\Fig. 3A is a, top view' of the arrangement according to Fig. 3. I

Referring now to the drawings, and particularly to Figs. 1 to 13, a support according to the invention comprises a hollow tubular standard I mounted on abase plate 3; provided with coasters to be displaceable along a pair of rails .5. A sleeve 2 is vertically slidable onthe standard I and includes as an integral part thereof a hollow arm projecting at right angles to the standard I and to the rails 5. A horizontal rod 3 has one end thereof rotatably inserted into and carried by said hollow arm while on the other end of the rod 3 in a vertical plane parallel to and on one side of the rails 5, there is mounted the photographic equipment. The photographic equipment includes, for instance, two pairs of telescoping tubes 6, the outer tube of each pair being secured to the rod 3, a frame I carrying a luminous screen, an extension bellows 3, a casing 9 for the cinematographic or other photographic camera, a support In for said casing secured to the right hand ends of the telescoping tubes 6 and an electromagnetic switch H for operating the camera in the casing It.

The weight of the sleeve 2, arm 3, photographic equipment 6-H and of the camera is counterbalanced by a Weight (not shown) which is slidable within the standard I and connected withthe'sleeve 2 by means of a chain 12.

In Figs. 1, 1A and 1B, the horizontal rod 3 is adjusted to a position in which the telescoping tubes 6 and the bellows 8 of the photographic equipment extend in a substantially horizontal direction, while in Fig. 1C, the rod 3 has been turned through 90 about its own axis in the hollow arm of sleeve 2, to bring the tubes 6 and bellows 8 of the photographic equipment into the vertical position shown.

Figs. 2 and 2A show an arrangement including, in addition to the support elements [-5 for the photographic equipment 6-! I, a second according to the invention comprising, in addi- 55 similar standard 13 with a sliding sleeve l5 connected by means of a chain l4 to a counterweight (not shown) which slides inside of the standard l3. A rod 11, rotatable in a hollow arm integral with the sleeve l5, carries the X-ray tube l8 and two telescoping members l6 adapted to be connected with their ends to the frame I of the photographic equipment (see Fig. 2A) The standard 13 is erected on a base plate l9 provided with coasters to run on a pair of rails 20 extending parallel to 'and"ata' distance'from the'pair of rails 5. The hollow arm and horizontal rod 3 project from the standard I at right angles to the rails 5 and towards the rails and the hollow arm and horizontal rodfl project from the standard l3 at right angles to the rails 20' and toward the rails 5, the photographic equipment 6-H and the X-ray tube I8 being mounted on the rods 3 and I1, respectivelyflin such a manner that their focal axes are disposed -in-- A control mechanism for the standard l3 carrying theX-ray' tube-l8 includes an endless cable 24 secured to thebase'plate I9 (see Fig. 2) and running over two fixed pulleys 23 and 25, the latter being rotatable over a third-pulley 26 by means of. a crank 2T. .In Figs. 2' and 2A the X-ray tube l8'and the photographic equipment 6-H are adjusted to positions'in which their focal axes extend in a substantially horizontal plane, and the X-ray table 2!, 22 is in its inoperative position at the righthand end of the rails 28;

According'to'Figs. 3 and'3A, the sleeve 2 on standard I is shifted to a higer level and the sleeve- IS on standard l3 to' alower "levelywhile the two horizontal-rods 3 and 11 are turned in their hollow support arms to angular positionsin which the focal axes ofthe :X-raytube l8 and of the photographic equipment 6"-I l are disposed in a-common inclined plane." The X-ray table 2|, 22 is-shifted to a position between the rods 3 and l'landthe table top22 is tiltedto extend between the X-ray tube l8 and the frame 1 at substantially right angles to the inclined focal plane.

It will be seen that in the arrangement set forth each element, X-ray tube, photographic equipment and X-ray table, can be used separately and independently or in combination with any one or all of the other elements. Whenever a -combination of; two Onmore elements is to be effected; the desired elements are shifted along their rails into the proper positions without any lateral adjustment because the focal axes of the X-ray tube and of the photographic equipment are invariably disposed in a common vertical planewith the longitudinal center line of the X -ray table top so that only the mutual distances, the height and the angular inclination of the elements need be adjusted. These adjustments can be easily and accurately effected owing to the construction of the support standards set forth.

1. Asupport arrangement for an X-ray tube and film-photographic equipment to cooperate with said X-ray tube, comprising two pairs'cfrails arranged parallel to and at a'distance from eachother, twdbase plateshaving coasters 'to run on'said' two pairs ofrails',respectively; a standard erected-"oneach of said 'base plates, means adjustable on and projecting from 'one of saidstandards-to support *an X-ray tube with its focal axis in a predetermined-"vertical plane extending parallel to and between said two pairs of rails, and means adjustable on and projecting from the other standard to support a photo-' graphic equipment with its"focal"axis in said same predetermined plane.

- 2: A support arrangement, as claimed in claim 1, in which said means for supporting the X-ray tube includes-two telescopingmembers extending in verticalplanes parallel'to'and equidistantfrorn said predetermined plane, said telescoping members being adapted to be' connecte'd to the photo graphic equipment to fix the relative positions of said X-ray tube and photographicequipment:

-3. A support arrangement; as claimed lnclaim 1, including a thirdpair'"ofrailsextending parallel to and between sai'd'firsttwo pairs of rails, and an ad-justable'X-ray table supported on and displaceable along-said thirdpair pfTalls.
